SMUGDESK SFF-8654 8i 74-Pin to Dual 4i 38-Pin SAS 4.0 Cable 40cm

SKU CH-15XK-0VPFG

A PCIe 4.0 breakout cable splits one SFF-8654 8i 74-pin port into two SFF-8654 4i 38-pin connectors for NVMe storage in compact servers

  • PCIe 4.0 compliant for high-bandwidth NVMe storage
  • Single 74-pin 8i port splits to dual 38-pin 4i connectors
  • Ultra-slim low-profile design saves space in compact servers
  • 40 cm short length optimised for tight internal routing
  • Precision impedance-matched wiring minimises signal loss and interference

Ultraport Slimline Breakout Cable

This SMUGDESK cable converts a single SFF-8654 8i 74-pin port into two SFF-8654 4i 38-pin connections. It serves technicians building dense NVMe storage arrays inside compact servers and workstations where internal space is limited. The 40cm length suits short internal runs in small-form-factor and rackmount chassis.

Ultraslim Profile for Airflow

The low-profile design reduces cable bulk, leaving more room for airflow around drives and controllers. Precision impedance-matched conductors minimise signal loss and crosstalk across the link. This construction supports stable PCIe 4.0 transmission speeds for high-bandwidth storage workloads.

Four-Lane Headroom per Port

Each 38-pin branch carries four PCIe 4.0 lanes, feeding NVMe SSDs or controller ports without bottlenecks for typical enterprise drives. The 40cm reach limits deployment to adjacent backplanes or nearby controller cards within the same enclosure. Builders needing longer runs or more than two endpoints must source different cables.

Questions about this item

Will the 40cm length strain the 74-pin or 38-pin connectors after repeated drive swaps?

The short 40cm run reduces torque on both the 74-pin and dual 38-pin ends, so normal drive swaps do not stress the solder joints.

Does the 4.0 signal rating hold when both 38-pin branches run NVMe drives at full speed?

Each 38-pin branch carries four lanes at PCIe 4.0 rates; the impedance-matched wiring keeps crosstalk low so the link stays stable under sustained load.

Will the ultra-slim jacket trap heat when the cable sits next to hot NVMe controllers all day?

The low-profile jacket adds minimal thermal mass and leaves airflow gaps, so heat from adjacent controllers dissipates normally.
